java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

잘돌아가던 이클립스에서 톰캣 실행 시 갑자기 class를 찾지 못한다는 오류가 발생하면서,

서버가 정상적으로 실행되지 않는 문제가 한번씩 생기는데...

두가지 경우 모두 maven dependency를 등록해주면 된다.

프로젝트 >> properties >> Deployment Assembly를 선택한 후,

"Add" >> Java Build Path Entries >> Maven Dependencies 선택한 후, "Apply"를 해준다.

톰캣 재시작하면 서버가 정상적으로 실행된다.

메이븐 메뉴에서 "Update Project Configuration"를 실행하는 경우,

해당 정보가 삭제되므로 다시 등록해주면 된다.
